Idle Cutoff

The position of the mixture control in a reciprocating engine fuel metering system that shuts off all fuel to the engine. Most aircraft have a mixture control that allows the pilot to adjust the fuel-air mixture to compensate for changes in air density as the aircraft gains altitude. When the mixture control is placed in the aft, or cut off position, all fuel is shut off to the engine, and it is starved of fuel, thus stopping.
